If you live on a block where the city has replaced lead pipes -- but you opted not to or don't know if the pipes on private property have been changed we'd like to hear from you. In addition, if you recently had your water tested for lead, what were the results?

E-mail us at tellus@wpost.com. If you're not certain whether your neighborhood might be affected you can check our block-by-block list from the CDC. There's also a map of planned and completed pipe replacement projects.
